Carrier CPHEATER052A00 Thermistor
A very basic thermistor is a thermal resistor, that has a varied resistance that is governed by current temperature. They convey to the main board when the temperature reaches a certain point. The control board needs to know the temperature throughout the whole system to make sure everything is running smoothly.
Simple signals your thermister needs to be replaced
- The main blower could never begin in its attempt to begin full speed blowing
- The whole HVAC system may not initiate the starting sequence because of the broken thermistor
